Microtubules, polymers of the heterodimeric protein αβ-tubulin, are indispensable for many cellular
activities such as maintenance of cell shape, division, migration, and ordered vesicle transport. In vitro
assays to study microtubule functions and their regulation by associated proteins require the availability of assembly-competent purified tubulin. However, tubulin is a thermolabile protein that rapidly converts into a nonpolymerizing state. For this reason, it is usually stored at -80 C or liquid nitrogen to preserve its conformation and polymerization properties. In this chapter, we describe a method for freeze-drying of assembly-competent tubulin in the presence of nonreducing sugar trehalose, and methods enabling the evaluation of tubulin functions in rehydrated samples.
